An Alice-Bob Kadomtsev-Petviashivili(ABKP) equation with shifted-parity(■_s^x parity with a shift for the space variable x) and delayed time reversal(■d, time reversal with a delay) symmetries is investigated. The multi-soliton solutions with three arbitrary even or odd functions are found from the ■_s^x■_d symmetry reductions of a coupled local KP system. The result shows that for the ABKP equation with ■_s^x■_d nonlocality, the odd numbers of solitons are prohibited.The solitons of the ABKP must be paired. For the ABKPⅡ equation, there exists a critical value of wave numbers for the existence of paired solitons. For the ABKPI equation, there are two types of 'breather' excitations. A lump solution of the ABKPI may possess four, five or six leaves. 展开更多

We study the phenomenology of a model that addresses the neutrino mass, dark matter, and generation of the electroweak scale in a single framework. Electroweak symmetry breaking is realized via the Coleman-Weinberg mechanism in a classically scale invariant theory, while the neutrino mass is generated radiatively through interactions with dark matter in a typically scotogenic manner. The model introduces a scalar triplet and singlet and a vector-like fermion doublet that carry an odd parity of Z2, and an even parity scalar singlet that helps preserve classical scale invariance. We sample over the parameter space by taking into account various experimental constraints from the dark matter relic density and direct detection, direct scalar searches, neutrino mass, and charged lepton flavor violating decays. We then examine by detailed simulations possible signatures at the LHC to find some benchmark points of the free parameters. We find that the future high-luminosity LHC will have a significant potential in detecting new physics signals in the dilepton channel. 展开更多

Reinforcement learning provides a cognitive science perspective to behavior and sequential decision making providedthat reinforcement learning algorithms introduce a computational concept of agency to the learning problem.Hence it addresses an abstract class of problems that can be characterized as follows: An algorithm confronted withinformation from an unknown environment is supposed to find step wise an optimal way to behave based only on somesparse, delayed or noisy feedback from some environment, that changes according to the algorithm’s behavior. Hencereinforcement learning offers an abstraction to the problem of goal-directed learning from interaction. The paper offersan opinionated introduction in the algorithmic advantages and drawbacks of several algorithmic approaches to providealgorithmic design options. 展开更多

The classical frustrated antiferromagnetic J1–J2 model is considered in a description of the classical spin wave for a vector spin system. Its ground state(GS) spin ordering is analyzed by minimizing its energy. Our analytical derivations show that all the spins in the GS phase must lie in planes that are parallel to each other. When applying the derived formulations to concrete lattices such as the square and simple cubic lattices, we find that in the large J2 region, a large continuous GS degeneracy concluded by a qualitative analysis is lifted, and collinear striped ordering is selected as the GS phase. 展开更多

Shanghan Zabing Lun,an acient book of Chinese medicine that published in Han dynasty(219 C.E.),is the first monograph in China that has the principles of prescription and treatment.Modern physicians flexibly applied many classical prescriptions recorded on this acientd book,such as Banxia Xiexin decoction,Da Chengqi decoction,Yiyi Fuzi Bijiang decoction and Wumei pill for the treatment of colorectal cancer and its complications,and made some progress in clinical and experimental research.Studies have shown that classical prescriptions alone or in combination with other therapies can improve immunity,prevent cancer from recurrence and metastasis,reduce the side effects of anticancer drugs,improve quality of life,and prolong the survival of cancer patients.However,the current clinical and mechanistic studies on the treatment of classical prescriptions still need to explore in depth.This study aims to summarize the clinical and research progress in the treatment of colorectal cancer with classical prescriptions in recent years. 展开更多

The classical washout algorithm had fixed gains and manually constructed filters, so that it led to poor adaptability. Furthermore, it lost the sustained acceleration cues of high-and mid-frequency in cross-over(tilt-coordination) channel, and the acceleration of cross-over frequency was also limited by angular velocity limiter, so the false cues in flight simulation process were clearly perceived by pilots. The paper studied the characteristics of the classical washout algorithm and flight simulator motion platform, tried to redesign the source of cross-over acceleration channel and translation acceleration channel, and transferred the part of cross-over acceleration that was unsimulated sustained acceleration to translation acceleration channel. Comparisons were mainly made between classical washout algorithm and revised algorithm in a longitudinal/pitch direction. The evaluation was based on the implementation of human vestibular perception system. The results demonstrated that the revised algorithm could significantly reduce the phase lag, and improved the spikes tracking performance. Furthermore, sensory angular velocity and the error of sensory acceleration were strictly controlled within the threshold of human perception system, and the displacement was a little broader than the classical washout algorithm. Therefore, it was proved that the new algorithm could diminish the filters parameters and heighten the self-adaptability for the washout algorithm. In addition, the magnitude of false cues was remarkably reduced during flight simulator, and the workspace utilization of the motion platform was developed by "closed-loop" control system. 展开更多

Classical swine fever virus(CSFV) is the causative agent of classical swine fever, a highly contagious disease of pigs. But there is little information on the recombination in natural populations of CSFVs. Therefore, a phylogenetic analysis of 62 fulllength genome CSFV strains, isolated from all over the world, was performed to detect potential recombination events, with the recombinant sequences being analyzed with the SimPlot and RDP programs. The results identified a mosaic virus, Chinese CSFV HCLV(2)(AF091507.1), which is the one naturally emerged recombinant CSFV with two recombination breakpoints at 2 484 and 2 900 bp of the genome alignment. Its two putative parental-like strains were CSFV Shimen(AF092448.2) and CSFV strain C/HVRI(AY805221.1). This work demonstrated that homologous recombination did occur in natural CSFV populations. It had significant implications for understanding the molecular epidemiology of CSFV, and revealed that recombination was an important factor for high genetic diversities of CSFV. 展开更多

In his famous 1982 lecture, Nobel laureate Richard Feynman seeded the idea of quantum computation. He reasoned that the amount of classical information required to describe a quantum system scaled exponentially with its size, and thus could not be efficiently simulated by a classical computer. Indeed, a fairly modest system of 100 quantum bits would already require more information to describe than all the present data storage on Earth[1]. 展开更多

This paper presents the rigorous study of mobile robot navigation techniques used so far.The step by step investigations of classical and reactive approaches are made here to understand the development of path planning strategies in various environmental conditions and to identify research gap.The classical approaches such as cell decomposition(CD),roadmap approach(RA),artificial potential field(APF);reactive approaches such as genetic algorithm(GA),fuzzy logic(FL),neural network(NN),firefly algorithm(FA),particle swarm optimization(PSO),ant colony optimization(ACO),bacterial foraging optimization(BFO),artificial bee colony(ABC),cuckoo search(CS),shuffled frog leaping algorithm(SFLA)and other miscellaneous algorithms(OMA)are considered for study.The navigation over static and dynamic condition is analyzed(for single and multiple robot systems)and it has been observed that the reactive approaches are more robust and perform well in all terrain when compared to classical approaches.It is also observed that the reactive approaches are used to improve the performance of the classical approaches as a hybrid algorithm.Hence,reactive approaches are more popular and widely used for path planning of mobile robot.The paper concludes with tabular data and charts comparing the frequency of individual navigational strategies which can be used for specific application in robotics. 展开更多

This article,based on the English version of Li Bai's Classical Chinese Poem“Bring in the Wine”,explores the important position of cultural transmission in the English translation of the Classical Chinese Poem through the comparison of the cultural translation,and finally draws the rationality and feasibility of the creative translation techniques in the English translation of the Classical Chinese Poems.It points out that the alienation of the Chinese culture's external communication has ignored the reader's cultural acceptance ability and position of the western countries and regions dominated by the foreign countries.It is believed that in a long period of time,Chinese culture needs the translation of Chinese translators to dissimilation,the translation of foreign sinologists,domestication,and alienation,to meet the needs of different types of readers and to promote the Chinese culture to go out. 展开更多

The suspected cases of PRRSV in a pig farm of Shandong Province were conducted pathologic autopsy, RT-PCR amplification, and sequencing and analysis of PRRSV N protein gene. The results showed that the homology of the nucleotide sequences of protein N was 99.7% between the isolate and the classical strains (VR2332 and SD1), and 93.4% between the isolate and the highly pathogenic strains (JXA1, HuN4, SX-1 and TJM). The results suggested that the virus was classical PRRSV in the pig farm. The research would provide a reference for the diagnosis and targeted therapy of classical PRRSV infection in swine production. 展开更多
